Find relevant Mesh components for specific UI patterns and use cases (e.g., tables, forms, dashboards)
AI agents call search_components_by_use_case to retrieve information from Mesh Design System MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool searches and retrieves design system component information based on query parameters (use cases). It has no side effects, does not modify data, does not execute code or commands, and does not involve financial operations. It is purely informational/read-only access to a design system catalogue.
From the tool's definition The tool 'search_components_by_use_case' is described as finding and retrieving relevant Mesh components for UI patterns.
Attacks that exploit this kind of access
Find relevant Mesh components for specific UI patterns and use cases (e.g., tables, forms, dashboards). It is categorised as a Read tool in the Mesh Design System MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Mesh Design System MCP Server MCP server in PolicyLayer and add a rule for search_components_by_use_case: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Mesh Design System MCP Server. Nothing to install.
search_components_by_use_case is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the search_components_by_use_case rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for search_components_by_use_case. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
search_components_by_use_case is provided by the Mesh Design System MCP Server MCP server (lukeylias/meshmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
